Trait NetworkFilesystem 

pub trait NetworkFilesystem: Filesystem {
    // Provided methods
    fn network_configuration(&self) -> NetworkConfiguration { ... }
    fn open_file(&self, _inode: u64, _writable: bool) -> Result<NetworkFile> { ... }
    fn close_file(&self, _inode: u64, _file: NetworkFile) -> Result<()> { ... }
}

Additional lifecycle hooks for lazy network filesystems.

Namespace operations remain demand-driven methods on the parent Filesystem trait. The open/close lease allows explicitly downloaded files to use local I/O without giving Swift ownership of cache eviction.

Provided Methods

fn network_configuration(&self) -> NetworkConfiguration

fn open_file(&self, _inode: u64, _writable: bool) -> Result<NetworkFile>

Selects the data source for an open file.

Returning NetworkFile::Remote leaves reads lazy. Returning NetworkFile::Local guarantees the path remains valid until close_file.

Errors

Returns a positive Darwin errno if the file can’t be opened.

fn close_file(&self, _inode: u64, _file: NetworkFile) -> Result<()>

Releases a file lease after Swift has closed any local descriptor.

This is a suitable point to update last-access state or schedule cache cleanup.

Errors

Returns a positive Darwin errno if lease cleanup fails.

Dyn Compatibility

This trait is dyn compatible.

In older versions of Rust, dyn compatibility was called "object safety".
